HAME ATTACHMENT.

EPECIFICATIQN forming part of Letters Patent No. 341,404, dated May 4,1886. Application filed March 13, 1886. Serial No. 195,068. (No model.)

T 0 all whom it may concern.-

Be it known that I, CLARENCE E. CARR, of Andover, in the county ofMerrimac and State of New Hampshire, a citizen of the United States,have invented certain new and useful Improvements in Hame Attachments,of which the following is a specification.

My invention relates particularly to an improvement in that class ofhame attachments by means of which the tug is connected with the hame bymeans of a staple or a bolt and starts.

The object of my invention is to decrease the friction which is nowlikely'to occur between the edges of the tug and the lower start or thelower leg of the bolt or the eye ordinarily niounted thereon to whichthe holdback is in practice attached, thereby producing a moreconvenient and desirable device for this purpose than those now in use.

In the accompanying drawings I have represented at Figure 1, in sideelevation, the lower portion of a hame having an attachment of the kinddescribed, and provided with my improvement in the form now best knownto me. In Fig. 2 is represented in section a portion of the structureshown in Fig. 1, upon an enlarged scale; and Fig. 3 is a view inperspective of the anti-friction thimble, hereinafter described. In Fig.4 I have shown my invention as applied to a hamestaple.

In the drawings, A represents the hame; B,

the upper start; B, the lower start; 0, the bolt, and D the loose sleeveupon the bolt, to which the end of the tug is attached. All these partsare well known and in common use.

In Fig. 4, G represents the staple,which for the purposes of thisinvention I regard as the equivalent of the bolt and starts.

Upon the lower start,B, I mount a loose or anti-friction thimble orsleeve, E, interposed between the outer end of the start, or that partthrough which the bolt 0 passes, and the eye F, also loosely mounted onthe lower start, B,which I first adapt to receive the pole-strap orholdback-ring. The anti-friction thimble E, Ipreferably form with athickened portion at its inner end, as shown. This thimble comes underthe edge of the tug when the lat ter is folded around the sleeve 1)(commonly employed in connection with start and bolt attachments of thissort) or around the staple G, and at such a height as to furnish anantifriction or rotating bearing for this edge of the tug. In this waythe thimhle 1*. serves to keep the edge of the tug away from frictionalcontact with any fixed part of the device. or with any part contact withwhich would be likely to injuriously wear and thus deface and weaken thetug.

In connection with the anti-friction thimble, and to receive thepole-strap ring, I prefer to employ an eye, F, of peculiar construetion, as shown. This eye consists of a sleeve adapted to surround andturn freely upon the lower start at its inner end, or at that part nextthe hame, and in connection with this is formed the dependent andot'fset lug, as shown, suitably formed to receive the pole strap, ring.This offset I make outwardly, or so as to bring the line of draft of thepolestrap ring substantially midway of the length of the lower start,the inner face of the eye F, or that next the hame, being made plane. Itis obvious, however, that other wellknown forms of eye might be used inplace of that specially described in connection with the rotatingthimble.

Heretot'ore, in some cases, a holdback-eye formed in one piece with aloose sleeve has been used on the lower start or the lower leg of thebolt-staple in hames. This device, however, is objeetionable, in thatthe eye, being held rigid when in use and whenthere is a strain on theholdback, is apt to wear the lower edge of the trace badly. The rotatingthimble, however, shown by me herein, is always loose to move with thetrace and diminish friction, while at the same time it serves to keepthe hook away from any contact with the trace.

I claim- 1. In a hame attachment, the combination, with the upper andlower starts, 13 B, and the bolt 0, of the loose or anti-frictionthimble E, for the purpose set forth...

2. The combination of the starts B B, the In testiinony whereof I havehereunto subbolt C, the sleeve D, the antifriction thimble scribed myname this 4th day of March, A. D. E, and the pole-strap eye F, the saidthimble 1886.

E and eye F being mounted upon the lower CLARENCE E. CARR. 5 start, B,and the thimble E being interposed Witnesses:

between the eye F and the outer end of the JOHN M. SHIRLEY,

start, all substantially as set forth. GEORGE WV. STONE.
